How do i check if the "name" property of any element in drink_list matches any string in a seperate list (str_list)?

drink_list = [
    {
        "name": "Rum & Coke",
        "ingredients": {
            "rum": 50,
            "coke": 150
        }
    }, {
        "name": "Gin & Tonic",
        "ingredients": {
            "gin": 50,
            "tonic": 150
        }
    }]
str_list = ['Gin & Tonic’, 'Daquiri']

If you want to keep a list of all the names, do something like that:

>>> l = []
>>> for i in drink_list:
...   if i['name'] in str_list:
...     l.append(i['name'])
... 
>>> l
['Gin & Tonic']

You can also append and keep the whole drink dictionary, if you append i:

l.append(i)

Can also use a list comprehension:

>>> [i['name'] for i in drink_list if i['name'] in str_list]
['Gin & Tonic']

    drink_list = [
        {
            "name": "Rum & Coke",
            "ingredients": {
                "rum": 50,
                "coke": 150
            }
        }, {
            "name": "Gin & Tonic",
            "ingredients": {
                "gin": 50,
                "tonic": 150
            }
        }]
    str_list = ['Gin & Tonic', 'Rum & Coke', 'Daquiri']

    // make an empty list
    found_list = []
    
   // iterate over drink_list and check if value is in str_list or not
    for drink in drink_list:
        if drink["name"] in str_list:   
            found_list.append(drink["name"]) // append matched value in found_list
    
    print(found_list) // prints desired output in list

Output:

['Rum & Coke', 'Gin & Tonic']
